Emlog is an open source website building system. In 2.6.13 and earlier, the article publishing interface stores a path-traversal template parameter from api_controller.php without validation, and log_controller.php later checks file_exists and calls include View::getView($template), allowing an authenticated author to include an arbitrary local .php file when an article is viewed. No fixed version is currently identified.

Emlog is an open source website building system. In 2.6.13 and earlier, the admin backend user search module's keyword parameter from admin/user.php is processed with addslashes but not HTML-escaped before being rendered into the value attribute in admin/views/user.php, allowing reflected cross-site scripting in an administrator's backend session. No fixed version is currently identified.

Emlog is an open source website building system. Prior to version 2.6.11, direct SQL injection in article creation and update functions allows attackers to execute arbitrary SQL commands, potentially leading to complete database compromise, data theft, or system destruction. This issue has been patched in version 2.6.11.

Emlog is an open source website building system. Prior to version 2.6.11, insecure plugin upload functionality allows attackers to upload and execute arbitrary PHP code, leading to complete server compromise and persistent backdoor installation. This issue has been patched in version 2.6.11.

Emlog is an open source website building system. Prior to version 2.6.11, missing CSRF protection in critical admin functions allows attackers to trick authenticated administrators into performing unauthorized actions like system registration, plugin management, and configuration changes. This issue has been patched in version 2.6.11.

Emlog is an open source website building system. In versions 2.6.2 and prior, a path traversal vulnerability exists in the emUnZip() function (include/lib/common.php:793). When extracting ZIP archives (plugin/template uploads, backup imports), the function calls $zip->extractTo($path) without sanitizing ZIP entry names. An authenticated admin can upload a crafted ZIP containing entries with ../ sequences to write arbitrary files to the server filesystem, including PHP webshells, achieving Remote Code Execution (RCE). At time of publication, there are no publicly available patches.

Emlog is an open source website building system. In versions 2.6.2 and prior, a SQL injection vulnerability exists in include/model/tag_model.php at line 168. The updateTagName() function directly interpolates user input into the SQL query string without using parameterized queries or proper escaping ($this->db->escape_string()), making it vulnerable to SQL injection attacks. At time of publication, there are no publicly available patches.

Emlog is an open source website building system. Prior to version 2.6.8, there is a stored cross-site scripting (XSS) vulnerability in emlog comment module via URI scheme validation bypass. This issue has been patched in version 2.6.8.

Emlog is an open source website building system. Prior to version 2.6.8, the backend upgrade interface accepts remote SQL and ZIP URLs via GET parameters. The server first downloads and executes the SQL file, then downloads the ZIP file and extracts it directly into the web root directory. This process does not validate a CSRF token. Therefore, an attacker only needs to trick an authenticated administrator into visiting a malicious link to achieve arbitrary SQL execution and arbitrary file write. This issue has been patched in version 2.6.8.

Emlog is an open source website building system. In 2.6.6 and earlier, the delete_async action (asynchronous delete) lacks a call to LoginAuth::checkToken(), enabling CSRF attacks.
